Application tiled March 5, 1309, Serial No. 481,464. Renewed June 23,1913. Serial No. 775,418.

To all whom it may concern:

Bc itfknown that L Josemi Onisrnrrr., o citizen or' the United States,residing at Southbridge, in the county oi Worcester and State ofMassachusetts, have invented a new :and nsct'ul EyeTesting Device, ofwhich the 'following is a. specilication.

'.lhis invention relates' to a device for testing the eyes and it isdesigned asa substi tute for the traine having movable lensescoir'unonly used by opticiens tor this purpose and for the variousdevices which have been employed for supporting the object to beobserved.

T he principal objects ot the invention are to provide a simple,convenient and easily manipulated device whereby a patient can test hisown eyes in a very convenient inenner without the aid ot an optic/ian orother assistant, so that the machine een be set up in a store or otherpublic, place end operated 'by the public for a small charge; to providea construction in which the sight openings through which the patientobserves the o ject inside will be conveniently located; to provide asimple and convenient arrange ment of light and object to be observedinside the casing; to provide a simple, inexpensive, ond practicablearrangement for supporting an endless series of lenses in the casing;and generally to improve and simplify devices of this character'.v

Reference is to be had to the accompanyingr drawings, in 'which- Figure1 is e side elevation, oit one embodi ment of the invention. with a partof the 'wall removed to show interior construction;

and liig. 2 is an end view ont the same also partly broken away to showthe interior.

The device is shown as comprising a rectangular :frame 10 having enopening et one side closed by a door r11. 'Within this trame is aplatform 12 over which are supported a pluralityof wheels 13 and 13'each liavinp,- radiating spokes ll and lll. These wheels are arranged torotate freely in the casing and. to'support an endless carrier 15havingl two parallel series oit lenses .16 there on, the carrier having"openings 1'? registeringwith the several lenses.. The lenses themselvesare talren advantage o'l for pro peiling the endless chain or carrier asthe spokes le and lll are at e dlstence spart at their endssubstentially eouivalentto the width of tlielenses,so that the spokescome between each'two adjacent lenses. As, one

of the wheels is rotated by means of a shaft and handle 18 extendingthrough the casing end located on the righi-.hand side of the saine, allthe wheels will be rotated and the i endless carrier token around so asto bring the several lenses successively in front of the sight openings19 which are providedin the wheel 13 is formed of two disks havthe sightopening to the object, and above the object and within said frame islocated a lamp 23 designed to be energized by Ineens of a battery 24located under the platform`l 12 which is controlled by a turnbutton 25located in convenient position on the Same side of the casing as thehandle 18. i

llfach lens is provided with o number V27 which shows through an openingEZB-in the projection 20 so that when a person uses the device he consee what lens best suits his eye and take down the number andV thenorder his glasses or spectacles accordingly.

While l have illust-rated and described a preferred embodiment of theinvention', l am aware that-many modifications can be made therein by.any person skilled inthe. ort without departin from the scope of theinvention es expresse in the claims. There# fore, I do not wish to belimited to ull the features olf construction shown9 but What I do claimist,

1. In an 'eye testing device, the combinaf tion of o rectangularcasinghavin o, pro; jection at lone upper corner-t creo epa-1r ozt sightapertures in said projection locatedv on en inclination, an object to beseeliinthe casing, an endless carrier inthe casingextending intov andthroughl said pro}ect1on,

wheel located in said projection between said sightapertures and object,and ineans for operating the carrier.

In an eye-testing device, the combination of a rectangular` casinghaving a pair of sight apertures, an endless carrier inside the easingextending just behind said sight apertures7 wheels near three corners ofthe easing having radiating spokes for engag-v ing the endless carrier,and a fourth wheel located' directly behind the sight apertures andhaving two disks provided With spokes between them located near theirperipheries, each pair of spokes having a clear space between the same,whereby the inside of the casing can be observed throughthe sightapertures and through said fourth Wheel.

3. In an eye-testing device, the combina- `supporting the carriercomprising a skeleton tion of a easing having sight apertures at one ofits upper corners and located on an inclination, an endless carrierinside the casing extending just behind said sight apertures, threewheels within the casing having radiating spokes for engaging theendless carrier7 and a fourth wheel located directly behind the sightapertures and consis'ting of two disks havin-g radiating spokes locatedbetween them near their peripheries, whereby there will be noobstruction to the vision through said fourth Wheel.

In testimony whereof I have hereunto set niy hand, in the presence oftwo subscribing witnesses.
